LOOSE LEAF BOOK CONSTRUCTION Filed Feb. 16, 1934 Patented Oct. 30, 1934burrs rArEs PATEN QFFHIE This invention relates to loose-leaf bookconstructions and particularly to constructions especially designed foruse as loose-leaf recipe books.

The principal object of the invention is to provide a loose-leaf bookwhich is particularly adapted for use as a recipe book. In the design ofthe book, novel features have been provided, as outlined below.

First of all, the top cover and the bottom cover of the book areprovided with flanges which come together when-the book is closed toform a protecting wall for the leaves of the book and which separatewhen the book is opened to form a ledge around the leaves of the book toprotect the leaves from cooking ingredients that may gather on themixing table whereon the book is disposed while the cook is referring toit. In the construction disclosed, the flanges are so made that theiredges telescope within each other, to form a tightly sealed dust proofcasing when the book is closed which resembles a closed box isappearance and utility.

The back of the book is provided with caps or =ears which overlie partsof the flanges of the top and bottom covers and cooperate with theseflanges to make, a tightly sealed dust proof casing when the book isclosed, and to provide a continuous ledge when the book is opened.

Furthermore, the back is joined to the top and bottom covers by means ofpiano hinges having long pintle pins, and these are held in place by theears or caps of the back.

The construction is such that the book, when 35,, closed, is in thenature of a closed metallic box containing loose leaves upon which maybe printed recipes, and when opened, is in the nature of a flat metallictray containing recipe sheets which are protected by the ledge formed bythe flanges and caps or ears.

Other features of the invention will be readily understood uponreference to the following book in its closed condition and shows theback of the book together with a portion of the top thereof.

Referring to the drawing, it will be seen that the book comprises a topcover 10, a bottom cover 11, and a back 12, joined to one another by thepiano hinges 14 whose loops are interconnected by the elongated pintlepins 15.

Riveted to the back of the book, by means of rivets 16, is a ring setwhich includes a back piece 17 and a plurality of split rings 18, thering set itself being more or less conventional. Received within thecover formed by the parts 1015 heretofore mentioned, and held in placeby the rings, are a plurality of loose leaves 19 having perforations 20registering with the rings 18 and these leaves are adapted to haveprinted upon them any desired matter, such as recipes or the like.

The bottom cover of the book is provided with a flange 22 around threeof its edges, which flange extends up from the bottom a distancesubstantially half the height of the back 12. Similarly, the top 10 isprovided with a flange 23 which extends downwardly from the top to aplane slightly below the center of the back 12. The free edge of theflange 23 is rabbeted, as indicated best at 24, so as to telescope ornest within the free edge of the flange 22, the two flanges nesting toform a flush surface protecting wall for the closed book. A spring clip25, riveted to the flange 22, snaps over the rabbeted edge 24 to holdthe top 10 tightly against the bottom 11, when the book is closed.

The back piece 12 is provided with caps or cars 27, which project overthe flanges 22, 23, a considerable distance, enough to close the gap at28 left by these flanges where they terminate near the back of the book.These caps or ears cooperate with the flanges 22, 23, to form a dustproof casing for the book, when the book is closed, and to form acontinuous ledge around the leaves, when the book is opened.

It will be observed that the pintle pins 15 are prevented from shiftingout of their hinge loops by the caps or ears 27, the construction beingsuch that no parts can separate to destroy the utility of the book.

Now having described a preferred embodiment, reference is had to thefollowing claims which determine the scope of the invention, it beingunderstood that the invention is not to be limited to the embodimentdisclosed.

I claim:

1. A book construction comprising top and bottom covers, having freeedges, a sheet metal back joining the covers and hingedly connected bypiano hinges at its edges to free edges of the covers, the covers havingflanges on other free edges which cooperate with each other and with theback to form a closed protecting case for the book when the book isclosed, the flanges together forming a protecting ledge for the bookwhen the book is opened, the back having end caps bent up therefrom andwhich overlie portions of the cover flanges when the book is closed.

2. A book construction comprising top and bottom covers, having freeedges, a sheet metal back joining the covers and hingedly connected bypiano hinges at its edges to free edges of the covers, the covers havingflanges on other free edges which cooperate with each other and with theback to form a closed protecting case for the book when the book isclosed, the flanges together forming a protecting ledge for the bookwhenthe book is opened, the back having end caps bent up therefrom and whichoverlie portions of the cover flanges when the book is closed, and whichconnect the flanges to form a continuous ledge when the book is opened,the end caps restraining movement of the pintle pins of the hinges.

3. In book construction, a book binder com prising a sheet metal back,top and bottom portions hingedly connected thereto on opposite edgesthereof by piano hinges, and having 00- operating flanges on theirunhinged edges which come together when the book is closed to form acase and which form a protecting ledge for the interior of the book whenthe book is opened, the back having end caps bent up therefrom and whichoverlie portions of the aforementioned. flanges when the book is closed,and which connect the flanges to form a continuous ledge when the bookis opened.

5. In book construction, a book binder comprising a sheet metal back,top and bottom portions hingedly connected thereto on opposite edgesthereof, and having cooperating flanges on their unhinged edges whichcome together when the book is closed to form a case and whichform aprotecting ledge for the interior of the book when the book is opened,the back having end caps bent up therefrom and which overlie portions ofthe aforementioned flanges when the book is closed, the-hingesbeing inthe nature of piano hinges and having elongated pintle pins, which areretained inplace by the aforementioned caps. 1

6. In book construction, a book binder comprisingla sheet metal back,top and bottom portions hingedly connected thereto on opposite edgesthereof, and having cooperating flanges on their unhinged edges whichcome together when the book is closed to form a case and which form aprotecting ledge for the interior of the book when the'book is opened,the back having end caps bent up therefrom and which overlie portions ofthe aforementioned flanges when the book is closed, and which connectthe flanges to form a continuous ledge when the book is opened, thehinges being in the nature of piano hinges and having elongated pintlepins, which are re-v tained in place by the aforementioned caps.
